The microscopic study

Pirochromite (MgCr2O4) nanoparticles were successfully prepared in this study. During synthesis of the pirochromite nanoparticles, a sol-gel was prepared by using magnesium acetate and potassium dichromate as magnesium and chromium sources and by using stearic acid as the network.

Different pathways of bilayer disruption by the structurally related antimicrobial peptides cecropin B, B1 and B3, revealed by surface plasma resonance analysis of immobi-lized liposomes, differential scanning calorimetryof peptide– large unilamellar vesicle interactions, and light microscopic analysis of peptide-treated giant unilamellar vesicles, have been identified inthis study.

S100A1 is a typical representative of a group of EF-hand calcium-binding proteins known as the S100 family. The protein is composed of twoasub-units, each containing two calcium-binding loops (N and C). At physiologi-cal pH (7.2) and NaCl concentration (100 mm), we determined the microscopic binding constants of calcium to S100A1 by analysing the Ca 2+ -titration curves of Trp90 fluorescence for both the native protein and its Glu32fiGln mutant with an inactive N-loop.

High-resolution X-ray diffraction structures of integral membrane proteins have revealed various binding modes of lipids, but current spectroscopic studies still use uniform macroscopic binding constants to describe lipid binding. The Adair approach employing microscopic lipid-binding con-stants has previously been taken to explain the enhancement of agonist binding to the nicotinic acetylcholine receptor by general anaesthetics in terms of the competitive displacement of essential lipid activator molecules [Walcher S, Altschuh J & Sandermann H (2001) J. Biol. Chem. 276, 42191–42195]....

The uptake of five fluorescein labeled cell-penetrating peptides (Tat, Tat2, mutated-Tat, peptide vascular endothelial-cadherin and transportan) was studied in wheat immature embryos. Interestingly, permeabilization treat-ment of the embryos with toluene⁄ethanol (1 : 20, v⁄v with permeabiliza-tion buffer) resulted in a remarkably higher uptake of cell-penetrating peptides, whereas nonpermeabilized embryos failed to show significant cell-penetrating peptide uptake, as observed under fluorescence microscope and by fluorimetric analysis....
